This section GB/T 1303 Part 6.

The partial modification of the use of IEC 60893-3-4:2003 (2nd edition) "thermosetting resins for electrical industrial rigid laminated sheets - Part 3. Single Materials Specifications Item 4. phenolic resin laminate rigid requirements "(in English).

This section 60893-3-4 and IEC .2003 The differences are as follows.

a) Remove the IEC 60893-3-4:2003 "Preface" and "Introduction", the introduction of this part of the content into "foreword" in;

b) of Chapter 1, "program" has been modified, deleted the material meets note, increasing the scope of application;

c) delete the name Chapter 3. Examples of dimensioning content;

d) according to the actual needs of the country, supplemented with tolerance performance laminate raw plate width, length; PFCP type updated the "apparent Flexural modulus of elasticity, "" vertical layer to the compression strength, "" parallel layer to shear strength "," tensile strength "," adhesive strength "," frequency Dielectric loss factor, "" frequency dielectric constant "," 1MHz lower dielectric loss factor "," 1MHz dielectric constant "," resistance to tracking Index "and" density "of the performance requirements; PFCC type Added the" apparent flexural modulus of elasticity "," shear strength parallel to the layers, "" pull Tensile strength "," adhesive strength "," frequency dielectric constant "," resistance to tracking index "and" density "of performance requirements related to technical difference They are involved in different terms in the margin of a single vertical line identification;

e) The "Requirements" chapter of the press, "look", "size" and "flatness", "performance requirements," points written in the "supply requirements" as a separate chapter Write, while IEC 60893-3-4:2003 in Table 5 were modified, the contents of the memo included in the Notes to Table; Table 5 Test side Chapter 5, "test" into the law reg rewritten and adds test methods slats;

f) Remove the IEC 60893-3-4:2003 references.
